DETAILED DESCRIPTION OF THE INVENTION

Referring now to the drawings, the preferred illustrative embodiments ofthe present disclosure are shown in detail. Although the drawingsrepresent some preferred embodiments of the present disclosure, thedrawings are not necessarily to scale and certain features may beexaggerated to better illustrate and explain the present disclosure.Further, the embodiments set forth herein are not intended to beexhaustive or otherwise limit or restrict the disclosure to the preciseforms and configurations shown in the drawings and disclosed in thefollowing detailed description.

Referring to FIG. 1, an exemplary firearm is shown generally at F (inphantom). The firearm, F, may be, for example, a pistol, handgun,revolver, or the like. The illustrated firearm, F, according to anembodiment, is a pistol and is shown to include a barrel, B, one or morebarrel rail slot(s), S, a handle grip, H, and a trigger, T. An axis ofthe barrel, B, is shown generally at A1, according to an embodiment.Secured under the barrel, B, proximate the one or more rail slot(s), S,and forward of the handle grip, H, and trigger, T, is a firearm targetillumination implement, which is shown generally at 10, according to anembodiment.

According to an embodiment, the firearm target illumination implement 10includes a body 12, a removable mounting plate 14, an illuminationdevice 16, and one or more illumination device actuators, which areshown generally at 18 a-18 c. The body 12 may be constructed from anydesirable material, such as, for example, extruded aluminum, to impartmaximum strength and precision when the body 12 is machined. The body 12may also include a hard anodized finish to resist wear and preventcorrosion. The illumination device 16 may include any desirableillumination component. For example, the illumination component mayinclude a bulb 16 a (FIGS. 3A, 3B) having any desirable illuminationrating to provide, for example, a long-range or short-range flashlight.It will be appreciated that the illumination component is not limited toa bulb and may be, for example, a light emitting diode (LED), asuper-bright LED, or the like.

Referring to FIG. 2, an enlarged view of the firearm target illuminationdevice 10 is shown without the firearm, F. When the mounting plate 14 isattached to an upper portion 20 of the body 12, a generally U- orC-shaped channel 22 is formed that permits the firearm targetillumination device 10 to be secured to the firearm, F, proximate theone or more rail slots, S. Accordingly, it will be appreciated that thesecuring channel 22 provides a universal clamping deck that may beadaptably- and removably-secured to fit most tactile firearms with orwithout rail slots, S.

As seen in FIGS. 2-3B, the upper portion 20 of the body 12 is alsodefined to include at least a top side 24 and a channel wall 26. Themounting plate 14 also includes a channel wall 28 that is substantiallysymmetrical to the channel wall 26 defined by the upper portion 20 ofthe body 12.

As illustrated in FIGS. 2 and 4, the mounting plate 14 generallyincludes a profile, which is shown generally at 30. The profile 30 ofthe mounting plate 14 mates with a profiled surface, which is showngenerally at 32, of the body 12. The top side 24 of the upper portion 20of the body 12 is also shown to include a passage 34 for receiving asecuring tab 36 extending from a flexible thumb tab 38 of an end plate40, which is discussed in detail below.

Referring to FIGS. 3A-4, the mounting plate 14 is removably-secured tothe body 12 with at least one mounting screw 42. The one or moremounting screws 42 is/are inserted through one or more respectivemounting plate passages 44 and coil springs 46. The embodiment shown inFIGS. 3B and 4 includes one mounting screw 42 and the embodiment shownin FIGS. 1-3A includes two mounting screws 42. However, it will beappreciated that the firearm target illumination implement 10 mayinclude any desirable number of mounting screws 42. The followingdiscussion and illustrated embodiments of FIGS. 3A, 3B, 7A, and 7B areshown to include two mounting screws 42.

When removably-attaching the mounting plate 14 to the body 12, themounting screws 42 threadingly-engage a threaded mounting screw passage48 formed in the body 12 to draw the mounting plate 14 generally in thedirection of an arrow, X1, toward the body 12. The coil springs 46 arepositioned in the screw passage 48 and between an end 58 of the mountingscrew 42 and body 12 (FIGS. 5A-5B) to apply a force against the end 58of the mounting screw 42 generally in the opposite direction of thearrow, X1. Operationally, the coil springs 46 are compacted in the screwpassage 48 and may prevent the potential of the fusing of the mountingplate 14 to the body 12 as a result of ‘kick’ forces exerted by thefirearm, F. Additionally, the coil springs 46 bias the mounting screw 42in a force opposite the direction of the arrow, X1, to relieve thepotential of an over-tightening the mounting screws 42.

Referring to FIGS. 2 and 5A, a mounting screw 42 is shown in a positionthat secures the mounting plate 14 to the body 12. A substantiallyrounded, dome-shaped end 52 of a threaded locking pin 50 is shownfrictionally engaging a portion 54 of the mounting screw 42. Referringto FIGS. 3A and 3B, the locking pin 50 is threadingly-inserted into apassage 56 that is formed in the top side 24 of the upper portion 20 ofthe body 12. As illustrated, the locking pin 50 engages the portion 54at a substantially perpendicular angle.

The locking pin 50 is preferably inserted into the passage 56 after themounting screw 42 has been inserted into the mounting screw passages 48so that the locking pin 50 does not cause interference with theextension of the mounting screw 42 into the body 12 through the mountingscrew passage 48. Accordingly, the locking pin 50 is threadably-insertedinto passage 56 until the dome-shaped end 52 engages the portion 54 ofthe mounting screw 42.

Referring to FIGS. 5A and 5B, the portion 54 of the mounting screw 42 isnon-threaded and substantially cylindrical in shape having a diameter,D1, that extends from an end 58 of the mounting screw 42. A threadedportion 60 of the mounting screw 42 is generally shown to include adiameter, D2, that is larger than the diameter, D1, of the portion 54and extends between the end 58 and a head 59 of the mounting screw 42.However, it will be appreciated that the portion 54 may not necessarilybe cylindrically-shaped and may include any desirable shape, diameter,or texture.

Functionally, the locking pin 50 and portion 54 of the mounting screw 42provides a preventative means for fully removing the mounting screw 42from the body 12 when the mounting screw 42 is ‘backed-out’ (i.e.,threadably-removed) from the body 12. Referring to FIG. 6A, thedome-shaped end 52 of the locking pin 50 drags (according to africtional constant) on an outer surface 62 of the portion 54 when themounting screw 42 is threadably-removed from the body 12 according tothe direction of the arrow, X2, which is opposite the direction of thearrow, X1. The drag cause by the contact of the dome-shaped end 52against the outer surface 62 of the portion 54 is tactilely fed-back tothe operator that is threadably-removing the mounting screw 42, and,accordingly, the operator applies an adequate torque to the mountingscrew 42 to move the mounting screw 42 in the direction according to thearrow, X2.

Referring to FIG. 6B, as the mounting screw 42 is threadably-removed inthe direction of the arrow, X2, the locking pin 50 eventually engages anend portion 64 of the mounting screw 42, thereby interrupting the dragfeed-back of the locking pin 50 relative the threadably-removingmovement of the mounting screw 42 in the direction of the arrow, X2,across the surface 62. As illustrated, the end portion 64 effectivelyincreases the diameter, D1, of the portion 54 to include anotherdiameter, D3, that is greater than the diameter, D1, but less than thediameter, D2, of the threaded portion 60.

Accordingly, as illustrated in FIG. 5A, a first position of the mountingscrew 42 may be positioned at a first distance, Z1, as measured betweenan end surface of the head 59 of the mounting screw 42 and an outer wallof the body 12, and, as illustrated in FIG. 5B, a second position of themounting screw 42 may be positioned at a second distance, Z2, that isgreater than the first distance, Z1, as measured between the end surfaceof the head 59 of the mounting screw 42 and the outer wall of the body12. Thus, the first position of the mounting screw 42 shown in FIG. 5Asubstantially secures the mounting plate 14 to the body 12, and, thesecond position of the mounting screw 42 shown in FIG. 5B looselysecures the mounting plate 14 to the body 12 while the mounting screw 42at least partially engages the body 12.

In design, the location of the end portion 64 acts as an integrated,mechanical stop to tactilely provide feedback to an operator that themounting screw 42 has been adequately ‘backed off’ the body 12 to apoint that permits the mounting plate 14 to loosen and freely rest aboutthe mounting screw 42 proximate the mounting plate passage 44 withouthaving to fully remove the mounting screw 42 from the body 12. Thus, itis less likely for an operator to lose the mounting screw 42 when thefirearm target illumination implement 10 is removed from the firearm, F,as a result of at least partially leaving a portion of the mountingscrew 42 being threadably-mounted within the mounting screw passage 48formed in the body 12.

Referring to FIGS. 3A and 3B, to provide power for activating theillumination device 16, at least two energy cells are shown generally aC1, C2. The body 12 includes an opening, which is shown generally at 66,for accommodating passage of the cells, C1, C2, into respective energycell cavities 68 a, 68 b along respective axes A2, A3 that extend,respectively, through the energy cell cavities 68 a, 68 b. As such, thebody 12 provides storage of the cells C1, C2 along axes A2, A3 that areparallel to but not coincident with one another or the axis, A1, of abarrel, B, of a firearm, F. As such, the body 12 is formed to have agenerally compact shape including a width, W, that is approximatelyequal to or less than the width of a barrel, B, of a firearm, F. By“stacking” cells C1 and C2 vertically (as shown in FIGS. 2, 3A, 3B, 7Aand 7B), illumination implement 10 assumes a short longitudinal profileespecially suitable for pistols.

As seen in FIGS. 3A-3B, the illumination device 16 is shown to generallyinclude a bulb 16 a, an electrical conductor 16 b, a threaded portion 16c, a coil spring 16 d, and an o-ring sealer 16 e. The illuminationdevice actuator 18 a generally includes a threaded cap 70, an o-ringsealer 72, a substantially transparent portion 74 of glass, plastic, orthe like, a bulb shroud reflector 76, a first threaded support 78, athreaded rotary dial 80, a second threaded support 82, and a thirdthreaded support 84. The illumination device actuator 18 b generallyincludes a threaded cap 86, a switch button 88, a button housing 90, anda conical coil spring 92. The illumination device actuator 18 cgenerally includes the end plate 40 having a rotary dial 94. Theillumination device actuator 18 c also includes a cam 96, and a switchconnector 98.

Referring to FIGS. 7A-7B, the body 12 is shown to includes a first andsecond outer surface threaded portions, which are shown generally at100, 102 to respectively secure the illumination device actuators 18 a,18 b to the body 12, respectively. The rotary dial 80 of theillumination device actuator 18 a threadably-engages the first threadedouter surface portion 100, and the threaded cap 86 of the illuminationdevice actuator 18 b threadably-engages the second threaded outersurface portion 102. The securing tab 36, extending from a thumb tab 38of the end plate 40, is inserted through a side passage 104 of the bodyproximate the opening 66 so as to allow the securing tab 36 to at leastpartially pass through the passage 34 of the top side 24 of the upperportion 20 (FIGS. 3A, 3B) to permit removable-securing of theillumination device actuator 18 c to the body 12.

Referring to FIGS. 8A and 8B, the operation of the illumination actuatordevice 18 c is shown according to an embodiment. As illustrated,according to an embodiment, the switch connector 98 includes asubstantially U-shaped first conductor 106 and a substantially flat,planar second conductor 108. The first conductor 106 is generallyconnected to one of the cells C1, C2, by, for example, a firstconductive lead 110 (FIGS. 7A, 7B). The second conductor 108 isgenerally connected to one of the other of the cells C1, C2, forexample, by a second conductive lead 112 (FIGS. 7A-8B).

As shown in FIGS. 8A and 8B, the second conductor 108 is located in asubstantially fixed position about the second conductive lead 112.Conversely, the first conductor 106 is shown in FIG. 8A in a relaxedposition, and in FIG. 8B, in a stressed position. As illustrated, thefirst conductor 106 is moved to/from a relaxed/stressed position byrotational movement of the rotary dial 94 which is joined with cam 96 toform a single unit. To cause movement of the cam 96, the rotary dial 94includes at least one extension 114 (FIGS. 3A, 3B) that is fitted withina bore 116 (FIGS. 3A and 3B) formed in the cam 96. Accordingly,rotational movement of the rotary dial 94 translates into rotarymovement of the cam 96.

In operation, one or more fingers 118 of the first conductor 106function as a cam follower that traces a perimeter profile of the cam96. As illustrated in FIG. 8A, the first conductor 106 is in the relaxedposition as the fingers 118 trace the shape of the cam 96 so as to bepositioned substantially in a first channel 120 formed in the cam 96.Conversely, to place the first conductor 106 in the stressed position,the fingers 118 trace the shape of the cam 96 so as to be positionedsubstantially in a second, substantially higher, channel 122 formed inthe cam 96.

As illustrated, when the first conductor 106 is placed in the relaxedposition, the first conductor 106 does not contact the second conductor108, and conversely, when the first conductor 106 is placed in thestressed position, the first conductor 106 positively contacts thesecond conductor 108. Thus, the relaxed position of the first conductor106 creates an open circuit according to the circuit diagram of thefirearm target illumination implement 10, which is shown generally at200 in FIG. 9. Conversely, the stressed position of the first conductor106 creates a closed circuit according to the circuit diagram 200.Because extension 114 rotates freely in bore 116, dial 94 can be relatedclockwise or counterclockwise an indefinite number of rotations withouthitting a stop or the like. Thus, extension 114 can be accessed from theleft side or the right side and can accommodate any switch use rotatingpattern preference of any shooter.

As shown in FIG. 9, the circuit diagram 200 is generally a seriescircuit. The bulb 16 a is connected to the conductor 16 b, whichcontacts a positive terminal of the cell, C1, which is connected, inseries, to the second cell, C2. The button 88 of the illumination deviceactuator 18 b is an on/off momentary switch for de/activating the bulb16 a. Accordingly, the button 88 may also open and close the circuit200. As explained above, the rotary dial 94 acts as a permanent on/off,or, a momentary on, release off switch for closing and opening thecircuit 200 to respectively de/activate the bulb 16 a. Although notillustrated, it will be appreciated that the illumination deviceactuator 18 a may also include a rotary on/off switch similar to theillumination device actuator 18 c such that the bulb 16 a may bede/activated upon rotating a the rotary dial 80 to/from a first positionand second position.

As shown in FIGS. 7A and 7B, the threaded rotary dial 80 of theillumination device actuator 18 a functions in controlling the focus abeam of light, L, emitted from the bulb 16 a. Bulb shroud reflector 78may be shaped as a parabolic reflector having a focal point. Threadedcap 70, O-ring sealer 72, transparent portion 74, bulb shroud reflector76, first threaded support 78, and rotary dial 80 may all form a focusadjustment subassembly. All of the components of focus adjustmentsubassembly rotate in unison whenever rotary dial 80 is rotated. Whenbulb 16A is positioned at the focal point of bulb shroud reflector 76,beam L is grouped in its tightest possible beam pattern. FIG. 7B depictsbulb 16A positioned at the focal point of bulb shroud reflector 76. Whenrotary dial 80 is rotated such that the focal point of bulb shroudreflector 76 moves away from X3, X4, the focus of the light beam L willgenerally diverge (divergent light beam L shown generally in FIG. 7A).Because of the longitudinal compactness enabled by vertically stackingthe batteries, rotary dial 80 can be easily accessed and rotated withthe index finger of the user without necessitating that the user releasehis shooting grip on the pistol grip.

It will be appreciated that the general ambidextrous positioning of thebody 12 relative the firearm, F, imparts left/right handed, ambidextrouscontrol of the de/activation and focus of the light beam emitted fromthe bulb 16 a. As such, a left-handed or right-handed firearm operatormay, while holding the firearm, F, about the handle grip, H, operate thefirearm target illumination implement 10 and/or trigger, T, with thesame hand holding the firearm, F, about the handle grip, H. Accordingly,when a firearm operator holds the firearm, F, about the handle grip, H,the firearm operator may be able to reach and control the plurality ofillumination device actuators 18 a-18 c to de/activate and focus of thelight, L, with one or more of his/her digits extending from his/herhand, including, for example, his/her thumb, “trigger finger,” “middlefinger,” “ring finger,” or “small finger.” As such, the firearm operatormay utilize one hand to operate the firearm, F, and firearm targetillumination implement 10 while freeing his/her other hand during theoperation of the firearm and/or firearm target illumination implement10. If desired, the firearm operator may alternatively hold the handlegrip, H, and operate the trigger, T, with one hand while operating thefirearm target illumination implement 10 with the opposite hand.
